arte+7recorder does'nt open

arte+7recorder doesn't open. It was working cool yesterday and today nothing.
Here's the end of what's happening when I launch it by terminal:

 <div class="star-rating star-rating-readonly star-rating-on">
  <a>
  </a>
 </div>
 <div class="star-rating star-rating-readonly star-rating-on">
  <a>
  </a>
 </div>
 <div class="star-rating star-rating-readonly star-rating-on">
  <a>
  </a>
 </div>
 <div class="star-rating star-rating-readonly">
  <a>
  </a>
 </div>
</div>
</div>

Traceback (most recent call last):
  File "arte7recorder.py", line 495, in <module>
    app = GUI()
  File "arte7recorder.py", line 176, in __init__
    self.dl_resume(None, None, None)
  File "arte7recorder.py", line 430, in dl_resume
    data_time = self.dureeRE.search(page).group(1)
AttributeError: 'NoneType' object has no attribute 'group'

thank you for helping and mega big thanks for creating it...
